T-rex pygmy is named Nanuqsaurus, or "polar bear lizards" in the language of the Inupiat Alaska, this adult creature has an estimated length of six meter and weighs 450 kg. And the experts say, that the mini T-rex is very similar to the nearby cousin, the giant tyrannosaur, which doubled the size of Nanuqsaurus.

Part of the skull and the upper and lower molars of the mini T-rex was discovered by paleontologists from the Perot Museum, Dallas, Texas, in the southeastern part of the U.S. They found it while digging the remains of the other unidentified small horned dinosaur.

Anthony Fiorillo, who was found the Nanuqsaurus fossil in Prince Creek Formation, North Slope, Alaska, above the Arctic Circle. This discovery is not too surprising for paleontologists because they had suspected there was a predator in the Arctic due to the presence of tooth marks on the bones of horned dinosaurs. And the discovery of this mini Tyrannosaurus was published in the PLoS ONE journal. *** [EKA | FROM VARIOUS SOURCES | VOA NEWS]
